LOS ANGELES, CALIFORNIA.

TRACT)? Application filed January 13, 1914.

To all whom it may concern Be it known thatl, VVILLiAiiI A. RIDER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Tractor, of which the following is a specification.

This invention relates to a tractor adapted for a variety of uses, and among the objects of the invention, are to provide a short wheel base, thereby securing a minimum turning radius to support the frame of the tractor by a set of springs, which only ha e that particular duty to perform, and to support the load carried by means of another set of springs.

Another object is to provide a supporting means located directly over the rear axle of the tractor for supporting and drawing a trailer, and th provide radius rods extending from the said supporting means to the frame of the tractor, and constructed with shock absorbers.

Another object is to locatenafl ajnck shaft at the rear of the rear axle, and provide suitable gearing extending forward from the jack shaft to the rear wheels for driving the same, together with means extending rearwardly from the motor to the jack shaft for driving the latter.

A further object is to provide a cable means for steering the rear wheels of the trailer controlled by the movements of the tractor, and to provide means for taking up slack in the said cable, enabling the bolsters of the trailer to be set at various distances from the tractor to accommodate the length of the load.

Other objects and advantages will be brought out in the following description.

Referring to the drawings: Figure 1 is a side elevation of the tractor. Fig. 2 is a plan View of the rear portion of the tractor. Fig. 3 is'a longitudinal section through a shock absorber. Fig. 4 is an enlarged section on line a2*-a' Fig. 2. Fig. 5 is a side elevation of the tractor showing a trailer mounted thereon. Fig. 6 is a. plan view of the tractor and trailer, showing the angular movement of the rearwheels ofthe trailer.

of the rear axle 1, being supported on the rear ends of the side frame bare t. The rear end of the frame 4 is supported by a pair of springs 5, which are in turn supported on shaft 1. A pair of radius rods 6 have their front ends mounted on a shaft 1, and extend rearwardly to the ends of the casing 3. The propeller shaft 7 extends forward from the differential gear casing 3 to the engine. which is located within the hood 8.

lifounted above the springs 5 are springs 9, which support a load carrying frame 10, the rear ends of springs 9 being pivotally connected at 11 to the frame, and the front ends being pivotally'connected to pivoted hangers 12, the latter permitting the necessary elongation of the spring? when the frame 10 moves down. A socket 13 is supported directly over the axle 1, and in the center of f ame 10 by a bridge 14-,and draw bars 15' extend forward from the eyes 16 on the bridge 11 to eyes 17 on the cross bar 18 of the main frame 4, and each draw bar fis1longitmlinally extensible and provided with a barrel 1.) with caps 20 and 21 screwed on the ends thereof. A forked eye 22 is secured thereto by a nut 23. The draw bar 15 extends slidably through the cap 21, and

has a follower 2t screwed on its end inside the barrel 19. Compression springs 25 and 26 are arranged within the barrels on each side of the follower 24 and act to cushion the movemcnt of the follower 2-1 and attached draw bar 15 in both directions.

The differential gearing located.within the casing 3 has a jack shaft 27 vvhiohcarries sprockets 28, which are connected by chains 29 with sprockets 30 on the-driving wheels 2 for driving the latter. By- ,tlius locating the jack shaft 27 at the-rear of the rear axle, I am enabled to move the rear axle and wheels forward and comparatively close to the front wheels so that a short turning radius is secured.

Figs. 5 and 6 show the manner of carrying a trailer in which 31 designates the body of the trailer provided with rear whels 32,

which are mounted on an axle 33 pivoted at tending throng, h the eyes 37 are cables 38, the rear ends of which extend rearwardly under the body of the trailer 31, and are attached to the fifth wheel 39 of the trailer. The ables from the eyes 37 extend forwardly and are wound on reels *0 on shaft 41 having a ratchet 4-2. The capstan heads %3 enable the shaft 41 to be turned to take up slack in the cable. This enables the bolster of the trailer to be located at various distances from the tractor to suit thelength of the load. The cables, as clearly shown in Fig. 6, cross each other under the body of the trailer 31, and their purpose is to turn the rear shaft 33 in the opposite direction to that in which the tractor turns with relation to the trailer, and to cause the same relative angular movement for the purpose of reducing the radius of circle required to turn in. This is highly important in drawing a trailer.

By reference to Figs. 1 and 4, it will be seen that the weight of the trailer is carried entirely by the springs 9, thereby relieving the springs 5 from any duty in carrying other than the weight of the frame 4 and the regular equipment of the tractor. This is an important and valuable feature, as it enables the springs 5) to be made sufficiently stiff to carry the required load and permits the springs 5 to bemade light. If the same springs 5 were required to carry the load of the trailer. they would have to be so stiff thatthey would be practically of no effect in cushioning the regular frame and equiphient of the tractor when it was operated without the trailer.
